I mean if you take that approach and want to talk statistics, what's the likelihood that we live in a computer-generated universe. I think the argument goes something like "If it's possible to create computer-generated universes inhabited with artificial beings then (which are self-aware but not aware they're living in a computer-generated universe #us) then by logical conclusion there would be more of these universes than there are real universes (because who ever stopped at creating just one) and if we consider that our reality isn't something special and don't assume it's the real one... then statistically speaking aren't we most likely to be living in a fake world?
An interesting thought, not sure how much weights it holds though...
